Application led January 4I 1917. Serial No. 140,579.

To all whom it may concern.'

Be it known that l, UTTO E. SIMON, a citizen of the United States,` residing at Menno, in the county of Hutchinson, State of South Dakota., have invented a new and useful Ad- Y justable Socket-lNrench; and I do. hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a socket wrench, and has for its object to provide a device of this character which embodies novel features of construction whereby it can be adjusted to t different sizes of nuts.

Further objects of the invention are to provide an adjustable socket wrench which is comparatively simple and inexpensive in its construction, which can be quickly adjusted to iit any size of nut, which can be used upon either square or hexagonal nuts, and in which the movable jaw is held securely in operative position.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a front elevation of a socket wrench constructed in accordance with the invention, portions being broken away.

Fig. 2 is a side elevation thereof, portions being broken away and shown in section.

Fig. 3 is a transverse vertical sectional view through the upper end of the wrench.

Fig. 4 is a horizontal sectional view on the line 44 of Fig. 3.

Fig. 5 is a fragmentary view of the lower end of the wrench, showing a modified construction.

Fig. 6 is a. transverse vertical sectional View of the construction shown by Fig. 5.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of the invention, the numeral l' designates the handle which is provided at one end thereof with an integral and later .elly projecting iev The side .the hanf' dleat the back ofthe jaw 2 is provided with a longitudinally extending groove 3 which opens through the end of the handle and is undercut at the sides thereon The movable jaw 4 hasan opposed relation to the fixed jaw Y2,l and is comple/mental thereto, the working faces of the jaws being shown as provided with corresponding angular recesses 5 for engagement with corners of the nuts. dExtending longitudinally through the handle l is an adjusting bolt 6, said bolt projecting from opposite ends of the handle, `and one end thereof being provided at 7 with right and left hand threads, one set of the threadsu engaging the handle l, while the opposite set of threads engages the walls of an opeiiing in the movable jaw 4. At the opposite end of the handle l the projecting end of the adjusting bolt 6 is provided with a iinger piece S which can be easily grasped for the purpose of turning the bolt to adjust the movable jaw 4 toward or away from the fixed jaw 2. In this manner it will be understood that the distance between the jaws can be readily adjusted to tit the particular nut or bolt which it may be desired to operate upon. Projecting from the inner face of the movable jaw 4 at the back thereof is an integral or rigid tongue 9 which is slidably received within the before mentioned undercut groove 8 of the handle l, the side edges of the tongue being engaged by the undercut side walls of the groove so that the tongue is retained securely in position within the groove, although it is free to slide longitudinally therein. A pair of guide rods 10 project from the jaw 2 on opposite sides of the adjusting bolt and operw ate in corresponding openings 11 formed in the movable jaw 4. These guide rods 10 and tongue 9 serve to direct the movable jaw 4 in its in and out movements and to hold it firmly in operative position when the wrench is in use, so that there is nodanger of the jaw 4 wabbling or the bolt 6 becoming bent when excessive strain is placed thereon to turn a nut. The dove-tail groove 3 prevents the tongue 9 from. moving laterally in the groove, while the guide rods 10 prevent turning of the outer jaw 4 on the bolt 6 which would cause the tongue 9 to bind in the groove 3.

A slight modification is shown by Fig. 5, in which the iinger piece 8 is slidable upon the adjusting bolt 6, but has a keyed connecj tion 12 therewith. A spring 13 holds the finger piece yieldably against the end of the handle 1 and corresponding clutch faces 14 on the handle and linger piece then coper ate with each other to look the finger piece and adjusting bolt against rotation. When it is desired to adjust the wrench, the linger piece 8 is drawn outwardly against the action of the spring 13 to disengage the clutch faces 14. The adjusting bolt 6 can then be rotated to move the jaw 4 toward or away fromv the fixed jaw 2, as may be desired, and after the movable jaw has been properly positioned,

- the finger piece 8a is released and permitted to be forced against the end of the handle 1 by the springs'13. The clutch faces 14 then cooperate with each other to lock the wrench in an adjusted position.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

A socket wrench including a longitudinally extending handle provided at one end thereof with a laterally projecting fixed jaw and having a longitudinal undercut groove opening through the end thereof at the back of the fixed jaw, a cooperating movable jaw having an opposed relation to the fixed jaw, a longitudinally extending adjusting bolt having a threaded engagement with the xed and movable jaws for sliding them toward and away from each other, a dove-tail tongue projecting from the back of the movable jaw and engaging the undercut groove of the handle, and a pair of longitudinally extending guide rods projecting from one of the OTTOv E. SIMON.
